<p><strong>Line 2:</strong> PFBC uses PHP sessions in the validation process, so you'll need to ensure you have session_start(); in your 
webpage - before outputting anything to the browser.  If you forget, you'll be reminded by an error message displayed above your form.</p>

<p>PFBC has support for 32 form elements: Button, Captcha, Checkbox, Checksort, CKEditor, 
Color, Country, Date, DateTimeLocal, DateTime, Email, File, Hidden, HTML, jQueryUIDate, Month,
Number, Password, Phone, Radio, Range, Search, Select, Sort, State, Textarea, Textbox, Time,
TinyMCE, Url, Week, YesNo.</p>

<p><span class="label label-important">Important</span> In each of the example forms provided, you'll
notice that the form's prevent property is set to an array containing "bootstrap" and "jQuery".  This prevents
the css/js include files from being loaded a second time by PFBC as they're already being included in a header
file.  If your system already includes jQuery or bootstrap, it's recommended that you edit the prevent
property in PFBC/Form.php so you don't have to set it (the prevent property) each time you create a form.</p>

<p>PFBC supports 9 types of validation rules: AlphaNumeric, Captcha, Date, Email, MaxLength, Numeric, RegExp, Required, and Url.  Here's
how they are applied to elements.</p>

$form->addElement(new Element\Textbox("Require:", "Required", array("required" => 1, "longDesc" => "The required property provides a shortcut for applying the Required class to the element's\n\tvalidation property.  If supported, the HTML5 required attribute will also provide client-side validation.")));
$form->addElement(new Element\Textbox("Max Length:", "MaxLength", array("maxlength" => 10, "shortDesc" => "maximum of 10 characters allowed", "longDesc" => "The maxlength property provides a shortcut for applying the MaxLength class to the element's\n\tvalidation property.  It will also add the maxlength attribute for client-side validation.")));

Its constructor \n\tincludes two parameters: the regular expression pattern to test and the error message to display if the pattern is not matched.")));

	<h1>Ajax</h1>
</div>

<p>PFBC provides several properties and methods for facilitating ajax submissions.  To get started, you'll first need to set the ajax property in
the form's configure method.  The ajaxCallback property can also be included in the configure method if you'd like a javascript function to called
after the form's data has been submitted.  In the example below a callback function has been set to extract the latitude/longitude information from a
json response.</p>

<p>The validation process for an ajax submission also differs slightly from that of a standard submission.  If the form's isValid method 
returns false, you will need to invoke the renderAjaxErrorResponse method, which returns a json response containing the appropriate error messages.  
These errors will then be displayed in the form so the user can correct and resubmit.</p>

<?php 
$form = new Form("ajax");
$form->configure(array("prevent" => array("bootstrap", "jQuery"), "ajax" => 1, "ajaxCallback" => "parseJSONResponse"));
$form->addElement(new Element\Hidden("form", "ajax"));
